Koch Network Fuels Republican Push To Kill ACA Subsidies

As millions face higher premiums, Koch‑funded groups are pressuring Republicans to oppose Obamacare subsidy extensions.

As Congress races to determine whether millions of Americans will face higher health insurance premiums in January, a network of Koch-aligned advocacy groups is quietly driving Republican opposition to extending the Affordable Care Act’s enhanced subsidies through coordinated polls, letters, and pressure campaigns.

The Senate on Thursday failed to advance competing legislative proposals that would have either extended the enhanced premium tax credits or replaced them with Health Savings Account-style funding, leaving the subsidies on track to expire at the end of the year, potentially driving up costs for more than 20 million enrollees.

In recent weeks, the Charles Koch-founded Americans for Prosperity (AFP) and The Libre Initiative have waged a sustained campaign to steer Republican lawmakers away from the subsidy extension and toward Health Savings Accounts, the groups’ preferred alternative. On Dec. 11, AFP released a poll indicating voter support for Health Savings Accounts, while Libre Initiative issued a letter on the same day urging U.S. senators to oppose the tax credits. In the past month, both groups have repeatedly targeted the subsidies with blog posts, press releases, and vote alerts. Examples include a Dec. 9 post by AFP’s Dean Clancy criticizing the credits, a Dec. 10 AFP vote-scoring alert urging opposition, and a Libre blog post describing the measure as providing “little” for Latino families.

AFP’s lobbying disclosures show that the group, which spent more than $1.1 million on federal lobbying in the first nine months of 2025, has been meeting with members of Congress to push them on “supporting the expiration of Affordable Care Act premium tax credits.” Meta’s ad archive also shows that AFP has been spending tens of thousands on Facebook ads calling for the subsidies to expire.
